95 putting
have a 95 4dr 4X4 cpi with 199,000 miles on it. running pretty horrible lately. after reading threads on changing the CPI, i took to it. changed out the cpi and nut kit. all was well. took it for a test drive, still putting. ran some seafoam through the engine, and chnaged the plugs afterwards. still putting down the road. i have done a FULL tune-up and was wondering where i should look next.. thanks

Re: Re: 95 putting
Try pulling your EGR valve and check for carbons chunks. Clean it out with some brakelean and make sure the plunger is moving freely. Reinstall it with a new gasket. See if that helps.

Re: 95 putting
Did you check your vacuum hoses? Starting with the one off the back of the intake and going out from there.

Re: 95 putting
what brand plugs did you use ?
is it putting at idle or all the time? did you clean the IAC? any codes? hmmmm .... after a full tune up? hhmmmm ... you didn't mess with the timing did you? don't 95s need to be set with a timing-light? hmm ... you might try H20 decarbonizing, or another dose of seafoam ... Quote:

Re: 95 putting
Sounds like you've covered most things. Have you checked to see if the fuel pressure is low? Considered the possibility of a clogged cat? If your CPI was leaking, it could have killed your cat in no time at all.

Re: 95 putting
How about the cap and rotor?
Check the coil to cap wire as well, it tends to corrode in the coil end.

Re: 95 putting
Well I would take it to the driving range, get it to stop putting and start driving. Good grip and form are key, oh and the right set of clubs helps.
